YSM被破解了，但版权保护从来不是重点

讽刺的是，破解组表示，这次公开的破解甚至不需要攻克VMProtect本身。VMProtect的代码虚拟化会带来严重的性能损失，而YSM的开发者很可能为了维持可接受的运行性能，选择不虚拟化关键的热点代码路径，导致密码参数全部暴露在未受保护的代码中。到头来，费尽心思用C++重写的逻辑，核心部分竟然是不设防的。

多余的不去摘录了，感觉整篇文章能被省流的地方很少。了解 YSM 被破解本身请参见：https://github.com/OpenYSM/YSMParser

保守派：应该使用数字证书保护创作者的作品不被修改，也可以用来验证二进制产物的归属

中间派：应该学习 KSP 社区要求所有 mod 开源，以便于验证可信程度及便于他人接手

激进派：应该学习 F-Droid 做可重复性构建，保证二进制产物和源码一一对应
